Piranha Knives
Piranha Knives machines American automatics from aircraft-grade aluminum — fast, smooth, and unapologetically colorful.
The Excalibur OTF
Piranha's out-the-front dagger runs a 3.25-inch 154CM blade through anodized aluminum in silver, red, blue, green, black — even pink camo. Push-button speed with all-American build quality at prices below most premium OTF rivals.
California craft
Every Piranha is machined and assembled in the USA with action that snaps like a mousetrap and colors that make the display case pop.
Know your laws
OTF and automatic knives are regulated by state — see our Automatic & OTF guide before ordering, and compare the field in automatic knives.
